Curt Accessories and Parts - C56196


Used when a motorhome is towing another vehicle by way of a tow bar. If the towing vehicle has a 2-wire system and the vehicle being towed is on a 3-wire system (the vehicle has amber turn signals, separate from the brake signals), the vehicle to vehicle taillight converter will need to be used. This item cannot be installed backwards (the input going to the output side) to convert a tow vehicle down.

Note: The tail light isolating diode system (38955) will need to be used with the converter (C56196) to prevent power feedback.

Video Transcript for Curt Accessories and Parts C56196 Review

Today we're going to review part number C56196. This is the Curt Vehicle-to-Vehicle Tail Light Converter. Now this converter will adapt vehicles with the combined stop and turn light wiring, which is normally your 2-wire system, to separate turn and stop light, which is a 3-wire system. It's basically used when a motor home is towing another vehicle by way of a tow bar. Basically, if your towing vehicle has the 2-wire system and the vehicle being towed is on the 3-wire system, where the vehicle usually have amber turn signal separate from the break signals, this vehicle-to-vehicle tail light converter will need to be use. This converter cannot be installed backwards, meaning the input going to the output side to covert a tow vehicle down.

One note, though, they do recommend, when installing this, to use the tail light isolating diode system. We sell that separately on our website as part number 38955. It is listed on this product page as a related product. That will need to be used with the converter to prevent the power feedback. The maximum amperage on this unit, for the stop and turn lights, is 2.1 amps per circuit and for the tail lights it's 5 amps total. You see it comes with a nice set of instructions with details on how to make your connections.

Basically, what you would do is, on this side, the input side; it's even stamped on the converter input. It even describes what the wire is for. Basically your white wire will be ground, your yellow will be for your left side stop and turn. They're combined. The green will be for your right side stop and turn.

It will be combine. Then it will convert it down to the middle wire, which is the red break wire, which your break lights will be separate. Then the yellow will be your separate left turn. Then your green will be your separate right turn. That should do it for the review on part number C56196.

This is the Curt Vehicle-to-Vehicle Tail Light Converter.

I found a camper shell for my Ranger that had an LED brake light, but it had never been wired up before. Before I found this product I had simply spliced a connection into one of the vehicle's brake light circuits. While this DID work, it also meant that it would flash the turn signal from the side that I wired it into (I used the left side; Ford used amber turn signals on the Ranger from 1993 to 1999, but mine is a 2011). This would have confused anyone behind me whether I was slowing down, turning, or both with too many flashing lights at once. This tail light converter was the solution to this problem. An ordinary converter (3-to-2 wire) will NOT work b/c it can't be wired in backwards (tried it before on a similar project). Same for this one (it even says it on the labeling) except it works in the opposite direction (2-to-3 wire). I wired it in the same way as just the light itself, & nothing happened. Eventually I found out it needed power from the left AND right brake lights for it to function. EUREKA! Everything lit up when I pressed the brake pedal. I also found out that the hazard flashers run through the brake light circuit in the converter after being separated from the turn signals--the brake light still flashed along with them (but ONLY them); the same thing happens with the high-mount stop lamp on my Wells Cargo trailer, so I can live with that. Had to find extra wiring to reach the right side though. Only suggestions are to make the the input wires longer & explain in the instructions that you need the left AND right inputs for the converter to run properly. Otherwise an excellent product! 552854

Does exactly what it says, converts from combined turn signal/brake light to separate turn signal and brake light circuits. I am using it to pull a Bushtec motorcycle trailer (with separate brake light circuits, 6-conductor flat connector) with a motorcycle (with combined signal and brake light circuits). I just hooked it up in conjunction with a circuit isolator I already had wired in to a 4-condoctor flat harness tonight and it works. So now I have the 4-conductor connector for a rack I use instead of a trailer sometimes and the 6-conductor connector for the Bushtec trailer. The only drawback I have found is the third brake light on the spoiler of my trailer dims if I am braking and signaling a turn at the same time. It does this each time the signal flashes. But for the price, I'm happy with it. 294423

Does what it says it does. Internally, it uses a relay that triggers when both turn signal inputs are activated, so there is a pulse on the output when hitting the brakes, or when the cautions are activated. I used this to install turn signal / marker light combos on my trailer. This stops the brake light functionality from lighting up the turn signal portion of the marker lights, but there is still a brief pulse or strobe when the brakes are hit, or the cautions are activated. I would have personally used a mosfet in this unit instead of a relay, as the switching and signal processing would be orders of magnitude faster with no pulse or strobe effect. So, it does separate out the brake lights from the turn signals, but not 100%, more like 95% 388962

I recently purchased a new CanAm Spyder and had a trailer hitch installed to pull my small camping trailer. The Spyder output cable has combined brake and turn signal connections while my trailer has a separate turn signal and brake hookup. After calling Etrailer and speaking with Rick about my problem he suggested I use the C56196 converter. This small unit was exactly what I needed and it works perfectly. 186172

This item is exactly as advertised. I use it to convert a U.S. Spec vehicle with red turn signals to pull a E.U. trailer with the yellow turn signals and works like a charm. I have ordered several times from this company and continue to receive excellent service from the ordering processing all the way thru to the delivery. Would recommend both this product and the company to anyone asking. 526377

This is a well made product. I failed to order the required diode kit for the application I was using it for, so it did not work right away. I have ordered the diode kit and fully expect everything to be great. The customer service is extremely good and friendly. They really want to make sure customers are taken care of. 359181

I called to ask a some questions and the company was very helpful. We discussed the application I wanted to use the part for and recommended a different part that fit my needs better. The shipping was very fast also. I have not installed the part but, the instructions are clear and I will be putting it to use very soon. 432278

This convertor did exactly what I wanted it to do. The wires were clearly marked which made for easy installation. I rewired my trailer and wanted to put yellow turn signals on along with the red brake lights. I was able to use a standard 4 wire plug to my vehicle and the convertor did the rest. 194298

It works as described under normal circumstances, but I have one problem with the hazard flashing. Using it makes the brake lights light up on my trailer and not the turn signals like on the car. I still have to do some research on that issue. 421306

  • Wiring a Camper Shell Third Brake Light on a 2017 Chevrolet Silverado
  • I've never heard of an actual third brake light connector on a camper shell to plug in on a truck and we don't carry any parts to do that. The light generally needs to be hardwired into the truck's brake light circuit. The issue with this on your 2017 Chevrolet Silverado the brake light and turn signal circuits are combined on one wire. So if you just wire it in the camper shell's brake light will also flash with the turn signals. To solve this issue we recommend using a vehicle to...

  • Recommended Ball Mount and Hitch Ball for European Trailers
  • Thank you for your service. I would be happy to make some recommendations for you. An American style ball mount will work fine when we pair it with a 50mm Hitch Ball on a local trailer in Germany as long as you have a U.S. style trailer hitch on your vehicle with a 2 inch by 2 inch receiver. The look is different, but the function is the same. I'd suggest the MaxxTow Adjustable-Height Ball Mount, # MT70067. This will give you up to a 10 inch drop or a 8 inch rise to allow you to...

  • Separating Out Combined Turn Signals and Brake Lights to Use Light Bars with Separate Signals/Brakes
  • Both your 1998 Chevy C/K series pickup and 2011 Ram 1500 have combined tail light wiring systems. This means the turn signals and brake lights are on the same circuits. In order to get your light bars with separate turn signals and brake lights to function you just need to separate out those circuits on the vehicle using a converter such as # C56196. I have included a link to a video review of this converter for you. If the trucks have trailer connectors you can splice into the combined...

  • How to Separate the Turn Signal from Stop Lights on Trailer Wiring
  • Most trailer's are wired up so that the turn signals and the brake lights are carried on the same circuit. So what you are experiencing is normal, but there is a way to do what you are trying to accomplish. You will need to use a signal converter like # C56196. When you wire this to the trailer wiring you will get the stop light circuits separated from the turn signals. I attached a diagram that shows how it will install.

  • Rewiring a Car Trailer with Separate Turn Signals from Brake Lights
  • I can definitely help get you on track, but since wire colors on trailer wiring aren't always standard to a color code you will have to wire everything by function instead. Also, since he wants separate blinkers from stop lights he will have to install a converter for that like the part # C56196. I attached a chart that shows how this will wire to the trailer. The other picture I attached shows how a 7-way is typically wired on a trailer. The turn signal/brake wires will run from the...

  • Recommended Tail Light Converter For Trailer With Separate Wiring And LED Lights
  • I recommend the Vehicle to Vehicle Tail Light Converter, part # C56196 for your 2015 Highlander and trailer. The # 118158 will not work with the LED lights on your trailer. You will need to do some modifying of the trailer wiring to get this all to work. First, you will need to cut the trailer connector off and use a 4-way connector like part # HM48110. Connect the green wire to the green wire on the C56196 input, yellow wire to yellow input wire and white wire to white wire on the...

  • Isolating Brake Light Wire Signal for Additional Brake Light on Trailer
  • In order to isolate the brake light signal on your trailer when the stop and turn functions are on the same wire, you will want to use a tail light converter. I recommend the Tow Ready Tail Light Converter # 118158. This converter will install on the trailer's lighting system to allow you to add a single LED brake light, functioning like a CHMSL, on your trailer. The brake light signal can be isolated on the trailer, so you will not need to touch the vehicle's wiring in order to isolate...

  • How to Add a Third Brake Light to a Trailer
  • For adding a third brake light only to your trailer I recommend converter # C56196 because the Tow Ready one could have problems with an LED light. Converter # C56196 does the same thing; it takes combined turn signals/brake lights and separates them. In order to add a third brake light I recommend also using diodes, # RM-690 for one, to prevent any backfeeding or bleed over. You would splice a diode into the yellow and green wires on the converter. Then splice the yellow wire to the...

  • Options for Wiring Up Third Brake Light on Trailer Camper Shell on Toyota Tacoma
  • I wish it was just as simple as connecting to the 4-way circuit's but the problem is that there isn't a dedicated brake signal on your 4-way since the turn signals are combined on the brake signal circuit. You can try tapping into the third brake light signal of your vehicle as that will be your best option. Also, at the brake pedal there should be the same circuit available. You may need a circuit tester like part # PTW2993 for this if you do not have one. Or you can use a circuit converter...

  • 50mm Ball and Converting USA 4-Way on 2012 GMC Acadia to Work with a European Trailer in Europe
  • In Europe they usually use a 50mm ball such as # EH53C-C. The wiring is a little more difficult but we can help. You can use the 4-Way wiring already on your 2012 GMC Acadia but you will need to separate out the combined turn signal and brake light circuits. For that I recommend Curt converter # C56196. Then you would just need a European vehicle side trailer connector obtained locally to match what the trailer requires. Please note that you will likely need to split the running light circuit...

  • Will Curt Vehicle to Vehicle Tail Light Converter # C56196 Cause LED 3rd Brake Light to Blink
  • The Curt Vehicle to Vehicle Tail Light Converter # C56196 that you purchased (along with some additional trailer lighting) separates the combined stop/turn signals fed to it into discrete stop and turn signals that can be fed to the individual lights. Since your toy hauler has incandescent lights on it the addition of a LED third brake light should not pose any issues related to current demand. This vehicle-to-vehicle converter connects at the toy hauler lights at the rear of the trailer....

  • Wiring a Third Brake Light on a Camper Shell for a 2005 Ford Ranger
  • If you're needing to power a third brake light that's on a camper shell it will need to be wired into the truck's wiring. Use the Curt Tail Light Converter # C56196 to separate the turn signals from the brake light circuit. The red wire on the output side will then be wired to the brake light on the camper shell and the green and yellow will be capped off and not used.

  • How to Make a Quick-Disconnect Tail Light Converter For A Motorcycle Trailer Pulled by a Jeep
  • There is a way for you to be able to pull your trailer with both your 2003 Honda Goldwing GL1800 and your 1997 Jeep Wrangler. The first thing that is going on between these two vehicles is that the trailer is wired for a separate turn signal system where the brake lights and blinkers are on separate bulbs, whereas your Wrangler is wired to pull a trailer that uses a combined circuit where the blinkers and brake lights are on the same bulb. There is a converter that will allow you to...

  • Parts Needed to Run Combined Wiring to 3rd Brake Light on Truck Cap
  • If your truck has a combined lighting system where the stop signal is run on the same wires as the left and right turn signals then you can simply use the Vehicle to Vehicle Tail Light Converter # C56196. This converter separates the stop signal from the turn signals and will allow you to wire your 3rd brake light so that it will not blink when your turn signal is activated. To install it you will need to connect either the green or yellow wire to the appropriate turn/stop signal and...

  • How Can I Install Trailer Identification Lights With Little Clearance
  • The 3 LED Identification Light Kit for Trailers # MCL22RK3B have a 3 wire connection. This is because they are intended to be used as running lights and to light up brighter as brake lights. Because trailers use combined wiring, meaning the brake and turn signals are on the same circuit, if the wires are connected as brake lights, they will work as turns signals as well. Avoiding this is when you would need the Curt Vehicle to Vehicle Tail Light Converter # C56196. Another option,...

  • Troubleshooting Curt Tail Light Converter # C56196
  • Without more information, it would be difficult to say where the problem lies. If you are talking about the lights on your trailer, it could be due to the amount of lights you have on the trailer. Since any system and converters like part # C56196 have limits, there could be too much of a current draw causing the issue. If that is the case you might consider reducing the amount of lights you have on your trailer or changing to LED lights which require less current. If the lights all...

To prevent power from backfeeding into the circuits you will also need to use the Tail Light Isolating Diodes part # 48955.
